Decimal values in seek bar android -


i working on android application in using seek bar. in range 0 - 20 , starting value 5. numeric values working fine, want make decimal values range should 0.0 20.0. code numeric given below:

seekbar seek=(seekbar) findviewbyid(r.id.seekbar1);         seek.setprogress(5);         seek.setonseekbarchangelistener(new onseekbarchangelistener() {         @override         public void onstoptrackingtouch(seekbar seekbar) {         }         @override         public void onstarttrackingtouch(seekbar seekbar) {                         // todo auto-generated method stub         }         @override         public void onprogresschanged(seekbar seekbar, int progress,boolean fromuser) {         textview.settext( progress + " km");// + seekbar.getmax());         distance = progress;         }         });

xml seek bar:

<textview             android:id="@+id/txtseekbar"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_gravity="center"             android:layout_marginbottom="10dp"             android:text="5 km"             android:textappearance="?android:attr/textappearancemedium"             android:textcolor="@color/gray" />

i have used sample code decimal values not working. please me out here.

seekbar seek=(seekbar) findviewbyid(r.id.seekbar1);         seek.setprogress(5);           seek.setonseekbarchangelistener(new onseekbarchangelistener() {         @override         public void onstoptrackingtouch(seekbar seekbar) {         }         @override         public void onstarttrackingtouch(seekbar seekbar) {                         // todo auto-generated method stub         }         @override         public void onprogresschanged(seekbar seekbar, int progress,boolean fromuser) {          double value = ((float)progress / 20.0);         string yourprogress = string.valueof(value);         textview.settext( yourprogress + " km");// + seekbar.getmax());         distance = (int) value;         }         });

you should make progress range 0 200 , multiply current progress 0.1f when changes. cheers.

seekbar seek=(seekbar) findviewbyid(r.id.seekbar1);         seek.setprogress(5 * 10);           seek.setonseekbarchangelistener(new onseekbarchangelistener() {         @override         public void onstoptrackingtouch(seekbar seekbar) {         }         @override         public void onstarttrackingtouch(seekbar seekbar) {                         // todo auto-generated method stub         }         @override         public void onprogresschanged(seekbar seekbar, int progress,boolean fromuser) {          float currentprogress = progress * 0.1f;         string yourprogress = string.format("%.1f", currentprogress);         textview.settext( yourprogress + " km");// + seekbar.getmax());         }         });

in xml layout add progress bar

android:max="200"

when want getprogress multiply 0.1f

float currentprogress = seekbar.getprogress() * 0.1f;
